Comparison Of Resistance-Based Strain Gauges And Fiber Bragg Gratings In The Presence Of Electromagnetic Interference Emitted From An Electric Motor, Douglas Jr. Keller

Engineering

This thesis reports a performance analysis of resistance based strain gauges and fiber optic fiber Bragg gratings in an environment contaminated by high levels of electromagnetic interference. The obtained results are directly applicable to the development of aerospace vehicles propelled by electrical motors. An area of importance in this relatively new technology is characterizing the mechanical loadings coming off a propulsion device in a stationary setup. This characterization is usually accomplished through the utilization of load cells. The majority of the load cells used in such an application are based on measurements acquired through resistance strain gauges. However, electric motors …

Sub-Nanometer Coupling Distance Control And Plasmon Enhanced Carrier Generation And Dynamics In Iii-V Semiconductor Heterostructures, Sharmin Haq

Optical Science and Engineering ETDs

Plasmonic modes in metal nanostructures enable light confinement at subwavelength scales. This field confinement is important for exploring the potential of nanotechnology in miniaturization of optics as well as for the advancement of optoelectronic devices, such as photodetectors, photovoltaics, and light-emitting diodes. Plasmon resonances are also ideal for developing ultrasensitive biosensors, and for enhancing surface photochemistry and photocatalysis. The increasing number of plasmon applications requires fundamental understanding of the plasmon coupled system which has not yet been completely understood. Controlling and engineering the plasmon response at the nanoscale will open still more applications in material science, communications, biochemistry and medicine. …

The purpose of this work is two-part. The primary goal of this thesis is to identify a list of significant target insulin-like peptides (ILPs) that influence the maintenance of neuronal morphology in an aged animal model of Caenorhabditis elegans (C. elegans) and determine whether or not morphological changes have bearing on neuronal function. The second goal is to address and devise a solution for a common laboratory difficulty encountered within the research community, difficulty maintaining large age-synchronous populations of the model organism, C. elegans. Chapter 1 discusses the importance of insulin signaling and how it pertains to the morphology of …

Pantry: A Macro Library For Python, Derek Pang

Master's Projects

Python lacks a simple way to create custom syntax and constructs that goes outside of its own syntax rules. A paradigm that allows for these possibilities to exist within languages is macros. Macros allow for a shorter set of syntax to expand into a longer set of instructions at compile-time. This gives the capability to evolve the language to fit personal needs.

Pantry, implements a hygienic text-substitution macro system for Python. Pantry achieves this through the introduction of an additional preparsing step that utilizes parsing and lexing of the source code. Pantry proposes a way to simply declare a pattern …

Assessing Effects Of Climate Change On Access To Ecosystem Services In Rural Alaska, Helen S. Cold

Biological Sciences

Across the planet, climate change is altering the way human societies interact with the environment. Amplified climate change at high latitudes is significantly altering the structure and function of ecosystems, creating challenges and necessitating adaptation by societies in the region that depend on local ecosystem services for their livelihoods. Rural communities in Interior Alaska rely on plants and animals for food, clothing, fuel and shelter. Previous research suggests that climate-induced changes in environmental conditions are challenging the abilities of rural residents to travel across the land and access local resources, but detailed information on the nature and effect of specific …

Morphological And Phenological Responses Of Butterflies To Seasonal Temperature Increase In Alaska, Kathryn Margaret Daly

Biological Sciences

Climate is changing rapidly at high latitudes, and the responses of insects provide early indications of the impacts these changes have on biota. Butterflies (Lepidoptera: Papilionoidea) are among the best-known Subarctic and Arctic insects, and research in Greenland has revealed significant declines in butterfly body sizes along with advances in the timing of their first flights in spring. These changes are ecologically significant because smaller body sizes can lead to reduced fecundity in butterflies, and earlier adult emergence can have detrimental effects across trophic levels because Lepidoptera are an important food resource for birds and mammals. The primary goal of …

Distribution Of Hunter Groups And Environmental Effects On Moose Harvest In Interior Alaska, Tessa R. Hasbrouck

Biological Sciences

Moose (Alces alces) is one of the most valuable wild game resources in Interior Alaska. In recent years, residents of rural indigenous communities have expressed concern that climate change and competition from non-local hunters are challenging local moose harvest opportunities. I collaborated with wildlife agencies and village tribal councils to co-design two studies to address rural community hunter concerns. The first study assessed the spatial and temporal distribution of local and non-local hunter groups to examine areas of potential competition. The second study addressed changing environmental factors and their impacts on moose harvest. Although competition among local hunters or among …

Shining Light On Hibernator Genomes: Using Radiation To Reveal Dna Damage And Repair Dynamics In Arctic Ground Squirrels, Krysta L. Yancey

Biological Sciences

Mammalian hibernation is characterized by dynamic changes in metabolism and body temperature; it may be sustained for up to nine months in some species. The majority of hibernation is spent in torpor, a dormant state, which is regularly interrupted by brief periods of activity referred to as interbout arousal. Upon arousal thermogenesis begins in vascularized fat and ends with whole-body shivering until the animal reaches a body temperature around 36-37 °C. Interbout arousal is usually less than a day long and is commonly thought to be necessary for maintenance and repair of tissues, in addition to the cycling and replenishment …

Mass-Analyzed Threshold Ionization Of Lanthanide Imide Lnnh (Ln = La And Ce) Radicals From N–H Bond Activation Of Ammonia, Yuchen Zhang, Silver Nyambo, Dong-Sheng Yang

Chemistry Faculty Publications

Ln (Ln = La and Ce) atom reactions with ammonia are carried out in a pulsed laser vaporization supersonic molecular beam source. Lanthanide-containing species are observed with time-of-flight mass spectrometry, and LnNH molecules are characterized by mass-analyzed threshold ionization (MATI) spectroscopy and quantum chemical calculations. The theoretical calculations include density functional theory for both Ln species and a scalar relativity correction, electron correlation, and spin-orbit coupling for the Ce species. The MATI spectrum of LaNH exhibits a single vibronic band system with a strong origin band and two weak vibronic progressions, whereas the spectrum of CeNH displays two band systems …

Self-Stabilizing Token Distribution With Constant-Space For Trees, Yuichi Sudo, Ajoy K. Datta, Lawrence L. Larmore, Toshimitsu Masuzawa

Computer Science Faculty Research

Self-stabilizing and silent distributed algorithms for token distribution in rooted tree networks are given. Initially, each process of a graph holds at most l tokens. Our goal is to distribute the tokens in the whole network so that every process holds exactly k tokens. In the initial configuration, the total number of tokens in the network may not be equal to nk where n is the number of processes in the network. The root process is given the ability to create a new token or remove a token from the network. We aim to minimize the convergence time, the number …

Loosely-Stabilizing Leader Election With Polylogarithmic Convergence Time, Yuichi Sudo, Fukuhito Ooshita, Hirotsugu Kukugawa, Toshimitsu Masuzawa, Ajoy K. Datta, Lawrence L. Larmore

Computer Science Faculty Research

A loosely-stabilizing leader election protocol with polylogarithmic convergence time in the population protocol model is presented in this paper. In the population protocol model, which is a common abstract model of mobile sensor networks, it is known to be impossible to design a self-stabilizing leader election protocol. Thus, in our prior work, we introduced the concept of loose-stabilization, which is weaker than self-stabilization but has similar advantage as self-stabilization in practice. Following this work, several loosely-stabilizing leader election protocols are presented. The loosely-stabilizing leader election guarantees that, starting from an arbitrary configuration, the system reaches a safe configuration with a …

Comprehending flooding events and their risks is the first step in flood defense and can help to mitigate flood risk. Floodplain mapping is the first step towards flood risk analysis and management. Additionally, understanding the changing pattern of flooding events would help us to develop flood mitigation strategies for the future. This study analyzes the change in streamflow under different future carbon emission scenarios and evaluates the spatial extent of floodplain for future streamflow. The study will help facility managers, design engineers, and stakeholders to mitigate future …

Strategies To Customize Responsible Gambling Messages: A Review And Focus Group Study, Sally M. Gainsbury, Brett L. L. Abarbanel, Kahlil S. Philander, Jeffrey V. Butler

Research & Economic Development Faculty Research

Background Responsible gambling messages are widely used as a tool to enable informed choice and encourage appropriate gambling behavior. It is generally accepted that gamblers have different levels of risk of developing gambling problems and require various harm minimization tools and resources. Therefore, it is reasonable to expect that responsible gambling messages should be customized and target specific groups of gamblers. This project aimed to understand hypothesized differences between cohorts of gamblers and receive qualitative feedback on archetypal targeted messages used to increase use of responsible gambling tools. Methods Focus groups were held to test messages for specific cohorts: young …

Mobile Learning And Cognition, Helen Crompton, Diane Burke

Teaching & Learning Faculty Publications

The rise of mobile learning in schools during the past decade has led to promises about its power to extend and enhance student cognitive development – for example, by providing greater pedagogical opportunities for students (Mifsud, 2014). However, others claim that mobile devices are most often used to support traditional pedagogical approaches whereby students only passively consume content (Cochrane & Antonczak, 2014; Frohberg, Goth & Schwabe, 2009; Rushby, 2012). As schools invest resources in providing students with opportunities to use mobile devices as tools for learning, it is important to critically examine their use in practice.

Fine Scale Modeling To Estimate Human Exposures To Air Pollution, Fatema Parvez

Doctoral Dissertations

Traffic related air pollution is considered one of the major challenges for a large number of urban population. The rapid growth of the world’s motor-vehicle fleet due to population growth and economic improvement causes a significant negative impact on public health. As pollutants from roadway emission sources reach background concentration levels within a few hundred meters from the source, it is very challenging to implement a model that captures this behavior. Currently available air quality modeling approaches can compute the source specific pollutant fate on either a regional or a local scale but still lack effective ways to estimate the …

Pasnet: Pathway-Associated Sparse Deepneural Network For Prognosis Prediction From High-Throughput Data, Jie Hao, Youngsoon Kim, Tae-Kyung Kim, Mingon Kang

Faculty Articles

Background: Predicting prognosis in patients from large-scale genomic data is a fundamentally challenging problem in genomic medicine. However, the prognosis still remains poor in many diseases. The poor prognosis maybe caused by high complexity of biological systems, where multiple biological components and their hierarchical relationships are involved. Moreover, it is challenging to develop robust computational solutions with high-dimension, low-sample size data. Results: In this study, we propose a Pathway-Associated Sparse Deep Neural Network (PASNet) that not only predicts patients’ prognoses but also describes complex biological processes regarding biological pathways for prognosis. PASNet models a multilayered, hierarchical biological system of genes …

Exploring The Potential Role Of Late Stage Predation And Chinook Salmon Age Structure, Kaitlyn A. Manishin

Fisheries

Chinook salmon (Oncorhynchus tshawytscha) populations across the North Pacific have displayed a decrease in body size-at-return resulting from declines both in age- and body size-at-maturity. These changes have precipitated the loss of the oldest age classes in some populations and have occurred throughout the range of this species, suggesting a shared - yet currently unknown - driver in the common marine environment. A hypothesis for the cause of these changes is intense and/or selective predation marine mortality after the first winter in the ocean, potentially from predators selectively removing relatively large sub-adult Chinook salmon. Here I consider the question: under …

Factors Influencing Chinook Salmon Spawning Distribution In The Togiak River, Alaska, Stephanie L. Meggers

Fisheries

Salmonids are heavily dependent on specific habitat characteristics for survival, yet few studies in Alaska have examined the relationship between habitat and spawning distribution, using remote sensing approaches. To better understand the relationship between Chinook Salmon Oncorhynchus tshawytscha spawning distribution and environmental variables like habitat type (e.g., run, riffle, pool), temperature, and proximity to channel islands, optical and thermal imagery were collected on the Togiak and Ongivinuk rivers in southwest Alaska. Object-based image analysis was used to classify and quantify habitat types, while thermal characteristics and the proximity of spawning locations to channel islands were determined in a GIS framework. …

The Rational Basis Test And Why It Is So Irrational: An Eighty-Year Retrospective, James M. Mcgoldrick Jr.

San Diego Law Review

The Rational Basis test is one of the most common and yet perhaps the most insignificant United States Supreme Court test in the history of the constitution, yet year in year out clients and lawyers will submit another brief hoping against hope that this time there might be a meaningful outcome. There will not be.

This article attempts to explain why the rational basis test is so irrational in its outcome, why basic interests are disregarded in the name of judicial respect for the legislative process, and how easy it would be for there to be a better outcome. The …
